Let's Make Robots!

Where do I get it?

It's a free download from Microchip. That's the nice people who will also send you the free engineering samples.

CDs - Just plain old regular CDs

I have several thousand CDs. Mostly Microsoft updates and covers discs off magazines. These might make good wheels for robots. They definitely make good heads for robots.

Diodes, Signal, 1N418

I have about 100 1N418 signal diodes. I'm not desperately keen to get rid of them, so make me a good offer.

Jack Sockets, 3.5mm, Mono, Panel mount

THOUSANDS of these. Don't ask.

Magnetic Reed Switches (Aleph)

200 Aleph magnetic reed switches. You bring a magnet clsoe to them and the switch closes. Might be used for a rotation sensor or something.

Where does this stuff all come from?

Quasar 2.4GHz Transceiver

Has anyone ever seen or used this Quasar 2.4GHz Transceiver Module (QFM-TRX1-24G) or anything similar?

I like the price. I'm considering ordering a couple as an inexpensive alternative for controlling my I2C bus.

Looks like it's based on this TI chip whose data sheet gives better info than the Quasar data sheet.

3.3V Regulators Wanted

Anyone got any suggestions as to where I buy get free samples of 3.3V regulators, or where I can buy them cheaply? Does anyone have any they can give me or exchange for some of my crap?

Thanks.

National Instruments

At work, I use NI controllers to make test rigs which pretend to be jet engines. Here's some stuff other people have used them for:
